Answer #1

Since the concentration of two of these species are very large, their concentration will not change with time. However, since the order of the reaction is 1 with respect to the third species, its concentration will decrease exponentially with time.

Suppose a reaction with a single reactant is first order in that reactant. As a first-order reaction, the concentration of the reactant will decrease exponentially with time, and its half-life will be constant. Does the fraction of molecules that react per unit time change as the reaction progresses? Justify your answer. please justify with words and not just equations.
